Question

我正在尝试提取在特定日期拨打某些号码的次数。但是，尽管在Dialed_Num列上从varchar到int添加了强制转换，我仍然收到以下错误：“ varchar值的转换溢出了int列”是否有办法限制我提取的varchar值？我以为我还是会的，因为我只希望我在Where子句中指定的两个数字

SET NOCOUNT ON

DECLARE @StartDate date = '2018-09-01', @EndDate date = '2018-09-05'

SELECT

CAST (SEGSTART as Date) as LocalDay,
CAST(Dialed_Num as INT) as DIALEDMODNUM

FROM
oauser.cmsCallHistory cms

WHERE SEGSTART BETWEEN @StartDate And @EndDate AND [Dialed_Num] IN(6582000,6752000);

Answer 1

您的Dialed_Num列需要cast子句中的where。

SELECT
   CAST (SEGSTART as Date) as LocalDay,
   CAST(Dialed_Num as INT) as DIALEDMODNUM
FROM oauser.cmsCallHistory cms
WHERE 
   SEGSTART BETWEEN @StartDate And @EndDate 
AND 
   CAST(Dialed_Num as INT) IN(6582000,6752000);
